启动.net时弹出“当前用户没有安装MS Development Enviroment”解决方法

一、系统环境：Haproxy：172.16.19.103Web1:172.16.19.104Web2:172.16.19.106二、Haproxy安装[root@haproxy soft]# tar zxvf haproxy-1.4.22.tar.gz[root@haproxy soft]# cd haproxy-1.4.22[root@haproxy haproxy-1.4.22]# uname –a

[root@haproxy haproxy-1.4.22]#make TARGET=linux26 PREFIX=/usr/local/haproxy[root@haproxy haproxy-1.4.22]# make install PREFIX=/usr/local/haproxy三、修改haproxy配置[root@haproxy~]#cp /soft/haproxy-1.4.22/examples/haproxy.cfg /usr/local/haproxy/[root@haproxy ~]# vi /usr/local/haproxy/haproxy.cfgglobal log 127.0.0.1 local0 #全局日志 maxconn 4096 #最大连接数 chroot /usr/local/haproxy uid 99 #用户ID gid 99 #组ID daemon #后台运行 nbproc 1 #创建进程数 pidfile /usr/local/haproxy/haproxy.pid #pid文件defaults log 127.0.0.1 local3 mode http #支持的模式 option httplog #日志格式 option httpclose #请求完成后关闭http通道 option dontlognull option forwardfor #apache日志转发 option redispatch retries 3 #重连次数 maxconn 2000 balance roundrobin #算法类型

七、haproxy测试

[root@haproxy ~]# for i in $(seq 10); do curl http://172.16.19.103:8080;done
